Question

what are gass laws. Dervie an ideal gas equation​

Answer 1

Answer:

According to Boyle's Law, At constant n & T, the volume bears an inverse relation with the pressure exerted by a gas. According to Charles' Law, When p & n are constant, the volume of a gas bears a direct relation with the Temperature

Answer 2

The gas laws consist of three primary laws:

• Charles' Law- states that the volume of a gas is directly proportional to its Kelvin temperature.
• Boyle's Law- states that the volume of a gas is inversely proportional to its pressure.
• Avogadro's Law- states the volume of a gas is directly proportional to the number of moles.

The behavior of a gas under known conditions of pressure, volume and temperature is described by laws known as gas laws .

Gas obeying Boyle’s, Charle’s law and Avogadro’s law under the conditions of temperature and pressure is called an ideal gas.  

Derivation:-

V ∝ n [P, T constant] 

using Avogadro’s law ;

V ∝ T [n, P constant]  

using Charle’s law ;

V ∝ 1/P [n, T constant] 

using Boyle’s law  ;

now we can say that the combined gas law:-

V ∝ nT / p

or pV ∝ nT  

pV = nRT  

R = constant of proportionality / universal gas constant  .

The value of R =

R = 8.314 J mol-1 K-1
